It was a shop with the full dark room. I took it that is what you mean by dip n dunk. All I know anymore is I don't know.
Yeah, I meant my "avatar", the picture of Sysphus...
Dip and dunk, for film, is different from "manual printing" that you are thinking of (where you move the papers through the different chemicals manually).
Dip and dunk uses a large, light proof tank. A technician opens up your roll of film and attaches it to a large hangar that stretches the film out. The hangar is then "dipped" and "dunked" into each tank (developer, fixer, etc) down the line. The only mechanical contact with your film is at the ends, rather than in a roller machine (those atrocities you see at your local pharmacy) which is constantly in contact with your film. If not kept perfectly clean, scratches, inclusions, and tears can result due to the tension on the film strip.
Dip and dunk also allows for extremely precise control of the developer chemistry, rather than roll machines which are just charged up and recycled on a # of images basis.
Generally speaking, places that use dip and dunk are far more professional and dedicated to good quality. Many will use in-house distillers for their water; they run frequent samples of the chemistry, and many are certified by Kodak's Q-Lab or Fuji's (forget the name of it) lab certifcation program.
All of my film is dipped and dunked, period.
